Improved machine for cleaning and watering streets



of the bands Z' and y, passed over the pulleys a and rr on the shattJand the aforesaid shafts C and l.

'.lhe lower portionof the machine is surrounded by a stout cloth m -forpreventing the sweeper from throwing the dustwithout r the machine whenit is in operation.

The operation of my improved machine for cleaning the streets is asfollowsz' The forward movement of the wheels A will, through the bands@c y s and pulleys n', NV, s', t, a', and

fr, produce a rotation of the sweeper l and fan Cl in the direct-ionsindicated by arrows 1 and 2, the fan creating a strong suctioncurrentfrom the chamber l through the passage I and an equallystrongdriving-eurrent from the fan-chamber Il through the channel Ileading to the chamber l). 'lhe revolution et the sweeper drives thedust upon the apron' b in the direction of arrow 3 and within theinfluence of the suction from the fan, which drawsthe dust through thechamber l1 into the channel I, as shown by arrows 4 and 5.

`Issuing from thechannel I the dust enters the fan-'chamber Il at its'outerside and is ejected into the channel I', as shown by arrow 7,through which it passes, as shown by arrow 8, vand issues into thechamber I), as shown by arrow 9, Fig. 3, the finely-retienlated cover Spermitting the escape of the air, while the dust remains-in the chamberD, which when filled is emptied bythe door 1X.l 'It the rodf'i bedrawn,as indicated by arrow 10, the valve E will slide t'remV theopening t and the water with which the tank is filled 4willvpa'ss intothe pipe G and thence to the perforated discharging-cylinder F, fromwhich it issues in a multitude of .jets in the usual manner andsprinkles the street after it has been cleaned by the'sweepingarrangement.

Stones that may be thrown upon the apron b by the sweeper and drawn overits upper extremity by the suction of the fan' will fall removed by thedoor l. v The arrangement of the details of the noncssarily be asabovedescribed, as the most suitable'arrangement can only be arrived at byexperiment.

I do not claim the rotary brush or the apron, as such have been usedbefore in machines ol' this character. Neitherdo I claim of itself therevolving fan or blower; but

cover of said chamber l). v

In testimony whereof I have hereunto subnscribed my naine before twosubseri'l'aing uit;
